Projects/Skrooge

Skrooge is a personal finances manager for KDE4, aiming at being simple and intuitive. It allows you to keep track of your expenses and incomes, categorize them, and build reports of them. Web site KDE Application page source code

This page is dedicated to developers or advanced users who wish to have a deeper understanding of Skrooge.

Skrooge is part of KDE Extragear in the Office module

Compiling

Before we start, please consider using the nightly flatpak of Skrooge from the kdeapps remote, see community:Guidelines_and_HOWTOs/Flatpak. You should only be compiling yourself if you are making changes.

Another way to compile is using the the kdesrc-build utility. See community:Get Involved/development#Set up kdesrc-build

Get the Sources

First, you will need to get the Skrooge source code. There are two ways to do this.

Latest Release

You can download the archive file containing the source code, and extract its content using your favorite extraction tool, such as Ark.

Development Version

Skrooge code is stored in KDE's git system. It can be found in https://cgit.kde.org/skrooge.git

Read README

The README file in the source code probably has more up-to-date instructions on needed packages to compile.

Dependencies

To be able to compile and run Skrooge, you will need some additional components

KDE Headers

Skrooge uses KDE5 frameworks

Skrooge being a KDE4 application, it depends on many things in the KDE headers. You can get them from your distribution's packages (name usually contains KDE4+devel, KDE4+headers), or directly from KDE repositories.

QCA

Qt Cryptographic Architecture. Get it from your distribution packages.

libofx

A library to handle import for OFX files. Get it from your distribution packages.

Grantlee

Grantlee is a templating system, used to format the monthly reports. Get it from your distribution packages.

Build & Install

Place yourself in the directory containing the source code, and create a directory named "build" (This is useful to segregate built files from the source code). Open a Konsole in this directory, and run the following commands (as a normal user) :

mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix`
make

(please note the backquotes in the cmake command, they are important...)

Then, with root privileges:

make install

Uninstall

Tried Skrooge but didn't like it? Sorry to hear this... You can uninstall it by running this command in the aforementioned "build" directory, with root privileges:

make uninstall

Debugging

Trace activation

To activate traces, you need to export an environment variable in your console:

export SKGTRACE=XX

XX is the level of traces you want. It should be an integer between 0 and 20. The higher the number, the higher the quantity of information you get. 10 is good compromise.

Then, start Skrooge from this console. This will display a lot of information in your terminal, giving you hints as to what could be going wrong if you face issues.

Profiling

To activate the basic profiling mechanism included in Skrooge, you need to export an environment variable in your console:

export SKGTRACEPERFO=1 

Once Skrooge is started from this console, you can find two new commands:

• Restart profiling (CTRL+Pause) to initialize the profiling
• Open profiling (ALT+Pause) to open the result of the profiling

Profiling results look like this:

method , nb call , millisecondes , average , min , max , own time , average own time 
SKGMainPanel::setNewTabContent-addTab , 1 , 38.26897848 , 38.26897848 , 38.26897848 , 38.26897848 , 25.6370585 , 25.6370585
SKGObjectModelBase::refresh , 2 , 8.741794825 , 4.370897412 , 0.9698964357 , 7.771898389 , 8.147958875 , 4.073979437 
SKGMainPanel::setNewTabContent , 1 , 49.36599612 , 49.36599612 , 49.36599612 , 49.36599612 , 3.772916079 , 3.772916079 
SKGOperationBoardWidget::SKGOperationBoardWidget , 1 , 3.179117203 , 3.179117203 , 3.179117203 , 3.179117203 , 2.963078141 , 2.963078141 
SKGMainPanel::onOpenContext , 1 , 50.43999612 , 50.43999612 , 50.43999612 , 50.43999612 , 1.074000001 , 1.074000001
...

Remark: If SKGTRACE is set then you will be able to find the execution time of each methods in traces.

To profile only sql instructions, you can export an environment variable in your console:

export SKGTRACESQL=XX  

Only sql order with an execution time greater then XX ms will be displayed in console.

In the console, you will get something like:

executeSqliteOrder : SELECT t_name, t_TYPENLS, f_CURRENTAMOUNT, t_close from v_account_display WHERE (t_type='C' OR t_type='D' OR t_type='I' OR t_type='O') ORDER BY t_TYPENLS, t_name TIME='441 ms'
